Description
Technical field
The utility model relates to field of ventilation equipment, particularly relates to a kind of double-ended drum induced draught fan.
Background technique
Blower fan relies on the mechanical energy of input to supply gas side by side the equipment of body to improve gas pressure, be widely used in air inducing and the air-supply of boiler, current blower, induced draught fan are two kinds of separate blower fans, existing blower is mostly based on large-scale lasting induced draft type industry blower, its structure is single, power consumption is large, can only environmental gas be blasted in the chamber of needs, if mixed gas good for proportioning in advance will be blasted, or the words that the gas circulation in airduct utilizes, then need to support the use induced draught fan, add the load capacity of system, thus increase energy consumption.
Summary of the invention
According to above technical problem, the utility model provides a kind of double-ended drum induced draught fan of efficient energy-saving, comprise forced-and-induced draft fan body, it is characterized in that: described forced-and-induced draft fan body comprises motor, air-vent, air inducing filter screen, air inducing room, air inducing impeller, ventilating blind, blast chamber, blasting vane wheel, wind-guiding rib, air blast filter screen, blast orifice, described air-vent is connected with air inducing room, described air-vent and joint, air inducing room are provided with air inducing filter screen, the inside of described air inducing room is provided with air inducing impeller, the side of described air inducing room is provided with motor, described air inducing impeller is connected with the output shaft of motor, described blast chamber is communicated with air inducing room by ventilating blind, the inside of described blast chamber is provided with blasting vane wheel, the inwall of described blast chamber is provided with wind-guiding rib, described blast orifice is connected with blast chamber, described blast orifice and blast chamber joint are provided with air blast filter screen.
Described air-vent becomes 180 ° and arranges with blast orifice.
Described air-vent and blast orifice are flared type structure.
Described blasting vane wheel is installed by rotatingshaft.
The beneficial effects of the utility model are: the utility model uses ventilating blind blower, induced draught fan effectively to be combined, ventilating blind is both as the exhaust outlet of induced draught fan, also as the intake grill of blower, by air-vent, the gas in container or airduct is introduced air inducing room, and from ventilating blind through entering blast chamber, bloated by blast orifice, hold concurrently air inducing, air blast of such design is integrated, and uses a blower fan just can reach the effect of two blower fans again; And only air inducing impeller is connected with motor, the speed relying on the gas in air inducing room axially to flow into blast chamber drives blasting vane wheel to rotate, and decreases machinery input, thus reduces energy consumption.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
According to Fig. 1, the utility model is further described:
As Fig. 1, motor-1, air-vent-2, air inducing filter screen-3, air inducing room-4, air inducing impeller-5, ventilating blind-6, blast chamber-7, blasting vane wheel-8, wind-guiding rib-9, air blast filter screen-10, blast orifice-11.
Embodiment 1
The utility model comprises motor 1, air-vent 2, air inducing filter screen 3, air inducing room 4, air inducing impeller 5, ventilating blind 6, blast chamber 7, blasting vane wheel 8, wind-guiding rib 9, air blast filter screen 10, blast orifice 11, first motor 1 is arranged on the side of air inducing room 4 during installation, air inducing impeller 5 is arranged on the inside of air inducing room 4, then the output shaft of air inducing impeller 5 with motor 1 is connected, air-vent 2 is offered again on air inducing room 4, air inducing filter screen 3 is arranged on air-vent 2 and joint, air inducing room 4, then wind-guiding rib 9 is set on the inwall of blast chamber 7, blasting vane wheel 8 is arranged on the inside of blast chamber 7, blast chamber 7 is offered blast orifice 11, air blast filter screen 10 is arranged on blast orifice 11 and blast chamber 7 joint, finally the opposite side of air inducing room 4 is communicated with blast chamber 7 by ventilating blind 6.
Embodiment 2
During use, motor 1 starts, air inducing impeller 5 is driven to rotate, air-flow is sucked from air-vent 2 radial direction, air inducing room 4 is entered after being filtered by air inducing filter screen 3, the air-flow entering air inducing room 4 changes flow direction, axial flow, blast chamber 7 is entered through ventilating blind 6, the air-flow axially entered drives blasting vane wheel 8 to rotate, wind-guiding rib 9 makes the air-flow that moves axially decompose to periphery to scatter, avoid air-flow recoil and cause damage to blasting vane wheel 8, the blasting vane wheel 8 of rotation by air-flow by air blast filter screen 10, send from blast orifice 11.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
